IMPROVEMENT IN CORN-HUSKING MACHINES.

Specification forming part of Letters Patent No. 156,422, dated November3, 1874; application filed June 29, 1874.

To all whom it may concern:

Be it known that I, W. DAVIDSON J onus, of Hagamans Mills, in the countyof Montgomery and State of New York, have invented certain new anduseful Im oveinents in Corn- Huskers; and I hereby declare the followingto be a full, clear, and exact description of the same, referencebeinghad to the accompanying drawing making a part of this specification, inwhich Figure 1 represents a side elevation of the operating parts of amachine embodying my Fig. 2 is a plan perspective view of the same. Fig.3 is a side elevation of a section of the machine, illustrating theconcave guard attached to the hopper-strip; and Fig. 4 is across-sectional view of the revolving scrapers and the pendulous check.

This invention relates to certain improve-I ments in corn-huskin gmachines; and consists in one part of a concave guard secured to thelower end of an inclined hopper strip, placed between two pairs ofinclined husking-rollers arranged within a frame, in combination with arevolving recessed beater or separator suspended in bearings in theframe of the machine, and traversing the pairs of huskingrollers and theconcavity of the guard laterally and in such position that the recessesin the edges of the separator oppose the channels formed between theperipheries of the adjacent husking-rollers, and the plain-edge surfacesof the beater or separator when revolved describe a circle, the radiusof which is about one inch shorter than the radius required to describethe segment which forms the concavity in the concave guard, the objectsof this portion of the invention being to separate or single out one carat a time from the bulk of cars resting upon each pair ofbushing-rollers by throwing the bulk of ears back and up the inclinedrollers, and permitting but one car at a time to pass down the rollersthrough each recess presented to the rollers; also, to prevent thestopping, choking, or clogging of the machine by preventing the earswhich are thrown upon the hopperfstrip, either by the action of thebushing-rollers or the separator, from being caught between theseparator and the hopper strip. It further consists of a husking rollercomposed of a tubular iron shell provided with a tightly-fitting core ofwood, into which the teeth of the roller are driven through holesdrilled in the iron shell,

the objects of this part of the invention being to secure lightness anddurability, and to prevent the springing of the roller, which wouldgreatly impair the efficiency of the machine; also, to facilitate theoperation of repairing the roller when it becomes necessary to replacebroken teeth. It consists, in another part, of two or more consecutivependulous checks suspended over a pair of husking-rollers below thebeater or separator, and in such proximity to the said rollers as totouch lightly upon an ear of corn in its passage down the rollers andbetween them and the said cheeks,

the object being to prevent the ears of corn from jumping or flying upafter they have passed the revolving separator by a series ofindependent pendulous checks, no one of which can be effected by twoears of. corn at one and the same time. It consists, in another part, ofa revolving scraper or clearer, in combination with a pair ofhusking-rollers, the object being to clear the surfaces of the pair ofrollers of gum, juice, fiber, hnsks, or like matter that may adhere tothem, in consequence of the labor they perform. 1

In the accompanying drawing, the frame A of the machine is representedby full lines in Figs. 1 and 2. B and B are the huskingrollers, of whichthere are two pairs, pair 1 and pair 2, represented, that number ofpairs being sufficient to illustrate my invention. The roller B in eachpair consists of a cylindrical iron shell, y, the bore of which isfilled by a core, D, of wood, made by turning the wood to a size that itmay be driven into the bore of the shell 1, and fit it tightly. Holesare drilled through the shell y, and teeth 0 driven through the saidholes into the wooden core D, which latter retains them firmly in place.Should a tooth, 0, be broken or otherwise become injured, it may beeither withdrawn from or driven into the core D, and a new tooth, c,inserted in its place. The core D gives the shell y sufficient stabilityto prevent the roller B from springing, and lessens the weight and costof the machine. The roller B consists of a cylindrical iron shellprovided with holes 6, located therein in position toengage with theteeth 0 of the roller B. The rollers B and B of each pair have theirbearings in the frame A, are placed at an inclina tion, which causes thecorn to traverse them from their upper to their lower ends, and areconnected by gearing b b. The pairs 1 and 2 of rollers B B are separatedby a hopperstrip, E, extending the full length of the rollers B B. Uponthe hopper-strip E, at its lower end, and extending a short distanceupwardly therefrom, is placed and secured the guard E, the uppertermination of which is concave.

A revolving beater or separator, C, supported in bearings in the sidesof the frame A, and provided with recesses in its edges, traverses thepairs of husking-rollers B B and the concave guard E transversely. Therecesses in the separator 0 come directly over the channels formedbetween the rollers B B of each pair-1 and 2. The separator (J revolvesin the direction of the arrow in Figs. 1 and 3, and its edges inone-half revolution describe the circle shown by dotted lines in Figs. 1and 3, and its edges coming quite near to the curved surface of theconcave guard E. The plane surface of the guard E is parallel with thatof the hopper-strip E, and through the center of the shaft of theseparator 0.

Two or more pendulous checks, G, consisting of rectangular piecesof woodor other material, are suspended over each pair of bushing-rollers,below the separator U, and swing freely up and down in the channelformed by the side of the machine and the side of the concave guard E,and directly over the channel formed between each pair ofhusking-rollers.

- A revolving scraper or clearer, F, consisting of a shaft, I, providedwith wings to, having recesses 11 in their edges, is placed directlyunder each pair of husking-rollers, and connected to the gear-wheels b bby the pinions H H.

Owing tothe construction of the gearwheels I) and H, the scrapers Fperform about two and a half revolutions to one revolution of thehusking-rollers B B, and they are so placed in relation to thehusking-rollers that the edges of the wings 1.0 will scrape from thesurfaces of the said husking-rollers any foreign substances which mayhave adhered thereto. The teeth 0 of the rollers B pass through therecesses '12 in the wings to of the scrapers F.

The operation of the invention is as follows: Power being first appliedto the machine, unhusked ears of corn are thrown promiscuously, and inbulk, with a shovel or basket, upon the upper ends of the pairs 1 and 2of husking-rollers B B, and consequen tly in front of or above theseparator O. The teeth 0 of the rollers B B engage with the husks on theears of corn lying in the channels between the rollers B B of each pair,and start them loose and downward befrom the ear.

As the bulk of cars ride down the inclined rollers B B, the separator O,revolving upwardly, throws the ears not in the channel between therollers B B back up the incline, to be acted upon by the rollers B B,when the ears fall into the said channel. The husked or partly-huskedears in the channel between the rollers B B pass down the said channelthrough the recess in the separator G.

The concave guard E prevents the husked or partly-husked ears that jumpor fly upward, as they pass under the separator G, from being caughtbetween the edge of the separator and the top of the hopper-strip E,which would otherwise frequently occur, and stop the machine.

If an ear should fly upon the concavity in the'guard E, the sides ofwhich are perpendicular, it would be swept up the inclined hopper-stripE or the rollers B B, to be again acted upon, for the reason that thereis no place for the ear to rest upon, that it may be grasped by the edgeof the separator (1, nor is there sufficient space between the edge ofthe separators O and the concave guard E throughwhich an car may pass.

The husked or partly-husked ears, after they have passed the separatorG, ride under the pendulous checks G, which prevent them from jumping,and, in connection with the teeth 0 of the roller B, causes the ears torevolve spirally as they pass downwardly, thereby presenting every sideof the ear to the action of the husking-rollers.

The revolving scrapers or clearers F revolve at a-high rate of speed,and come so nearly in contact with each roller B and B of a pair as toeffectually clear the surfaces of the said rollers from all gum, fiber,&c., which may adhere to them in consequence of the labor which theyperform.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is-

1. The guard E, having concave face, and secured to the hopper-strips E,in combination with the revolving beater or separator O and rollers B B,constructed and operating substantially as and for the purposeshereinbefore set forth.

' 2. The corn-husking roller B, consisting of
